MPROVEMENT IN GANG-FLows.

The Schedule referred to n these Letters Patent and making part of the same.

To dll whom it may concern Be it known that I, GEORGE R. Curran, of the city, county, and State of New York, have invented an Improved Gang-Flow; and l dc hereby declare that the following, taken iu connection with the'drawin gs which accompany and form part of this specification, is a description of my invention sufficient to enable those skilled in the art to practise it.

The invention has particular reference to that class of gang-plows, in which the plow-beams or beam-frame forms part ofa wheel-carriage or truck-frtuuc, the plowheams or beam-frame having a capability of vertical movement relatively to the carriage-frame.

My invention consists primarily in hanging the carriage upon oue axle, so that it can be tipped freely at either end, the beams or beam-flame being hung to the front end of the carriage-frame, its rear part being suspended from the main frame behind the axle, and having provision for raising and lowering it.

The drawings represent a gang-plow embodying my improvements.

A shows the plow iu plan.

B is a vertical section on the line zx.

a denotes the main or carriage-frame secured to an axle, b, which is mounted upon high wheels c, the farriage tipping freely upon or with said axle, as will be readily understood.

To tbe front end of this frame is hung the plowframe (l, which, extending back beyond the axle b,'has timed to and depending from its beams e f g, the standards of the plowshares h 7. which form the plow gang.

Under the i'ont rail l of the frame (l, is a gauge-wheel, n, the spindle o, of the hearings of which passes through tbe front rail, it being secured in position by a screw, p, and the wheel being set atany desirable height, by raising or sliding down the spiudle.

As the.frout end of the plow-frame swings vertically, relatively to the axle b, the gangra-wheel n regu-' lates the depth of penetration of thc front plowshare, as seen ai, B.

Across the main l'itule, in rear of the axle, may extend a windiass-shaft, q, jourualled in hearings 7' 7', on the main frame. l

Around pulleys s s, uponthis shaft, are wound chains t t, tc the lower ends of which the rear end of the. plowfra-me is suspended, as seen at B.

By winding up the chains, by means of a windlass, 'u, or other suitable mechanism, the rear end of the plow-frame and the carriage-frame may be brought into the same plane, the plow-frame being held iu positionby a ratchet-and-pawl mechanism z Over the rear part of the two frames, is a long seat, w, connected at one end to the axle, and at the opposite end to the rear rail, x, of the main frame, as seen at B.

The operation of the plow is as follows:

The gauge-wheel n is first set to a height or distance above the plane of the lower surfaces of the plows equal to the depth to whicb'the furrow is to be cut. The wimllass-chains arc then looseued, letting the rear end of the plow-beams down; The carriage being now drawn forward, the front plow will penetrate the ground until the gauge-wheel strikes the surface of the ground, and all the other plows will enter the ground, and plow to thc same depth as the front onc, the beam-frame and the carriage-frame both yieldiug verticall y as circumstances require.

The driver sits upon the seat w, and by moving back upon the seat can readily tilt up the front end of the carriage-frame, and startthe front plow from the ground, or temporarily decrease its depth of penetration, while, by winding up the windlass-chaius and tilting up the front of the carriage, he can raise the whole gang of plows from the ground.

It will be seen that the plowshares all assume their V positions imlependeutly of the carriage-frame, the latter assuming such inclined position as will bring the lower surface of the two carriage-wheels c c, and the lower surface of the gauge-wheel n, into a, plane with the series of plowshares, at a height upon each, corresponding to the depth of penetration of all, as seen at B.

The draught-pole j is attached to the front rail of the beam-frame, and draws directly in the line of the beams.

The pole is hung to the rail by means of a rod running through eye-bolts y, and through eyes a-t the end of snap-pieces z, fixed to the pole; and hy means of thimbles or collars and set-screws the pole may be adjusted iu position later-ally, so as to cause the plows tc take morc or lesseland as desired.

1. I claim, n combination with the plow-beams or beam-frame, the tiltiug carriage frame, substantially as described. l

' 2. I also claim, with the tilting carriage-frame and the plow-irame pivoted to the front end thereof, the long seat extending from tbe axle to the rear of t-he carriage-frame, substantially as shown and described.

3. 1 also claim a gang-plow, having the plow-beams or beam-flame pivoted to the front end of the carriageframe, when the latter is arranged to tip relatively to the draught-pole, substantially as shown and described.
